Causality
The Irngrad listened to the opinions of the clans' chieftains. They were clearly divided heavily on whether or not to believe in Eisen's identity, but overall, in regard to the actual important topic at hand, it seemed as though they were leaning into a more singular direction. All of them were at least considering the warning that Eisen had told them. The ones that were already against the war to begin with were just strengthened in that belief, and those that supported the war, saying that they shouldn't let the central continent do whatever they please, were thinking a bit more deeply about the situation.
